python - “模块”没有属性 'Treestyle'

Question

如果在 stackoverflow 上发现一些点击，其中人们在未安装 PyQT4 时使用 ete3 工具时遇到问题，这(过去)也适用于我。然而，我现在尝试重新安装一个软件，它一直提示“模块”没有属性“Treestyle”。

为了测试 PyQT 是否已安装，我运行了这个 python 脚本:

from PyQt4.Qt import PYQT_VERSION_STR
print("PyQt version:", PYQT_VERSION_STR)

打印内容:

('PyQt version:', '4.12.1')

我收到这个(常见)错误:

Traceback (most recent call last):

  File "/mnt/f/mypy/local/lib/python2.7/site-packages/VirtualMicrobes/plotting/Graphs.py", line 1083, in make_tree_style
    ts = ete3.TreeStyle() 

注意:这一次我尝试将其安装在 Ubuntu for Windows 上，但到目前为止，几乎所有在 Linux 上运行的东西也都在这个上运行。但它可能是相关的。

有什么想法吗？

PS 要重现该问题，请按照以下步骤操作:

$ sudo apt-get install python-qt4
$ virtualenv ~/mypy --system-site-packages
$ source ~/mypy/bin/activate 
$ (mypy) > pip install VirtualMicrobes
$ (mypy) > virtualmicrobes evo --name TestMicrobes >> error

PPS 用户 eyllanesc 确认这是“Ubuntu for Windows”问题。不过，我仍在尝试修复它，如果有人可以帮助我弄清楚如何将 pyqt4 包正确链接到我的 virtualenv，那就太好了。我已经尝试使用 ln -s 链接 native 链接，但我没有得到任何进一步

我也遇到过类似的问题。问题可能是您没有安装所有依赖项，而 ete3 没有告诉您所有依赖项。

您可以查看此代码缺少哪些依赖项:

import ete3
ete3.__file__

运行它，它会告诉您缺少哪些依赖项。请注意，在安装全部之前，您可能需要运行它多次!
